EDGE-LINING MACHINE.

Specification of Letters Patent.

J atented Jan. 13, 1920.

To all whom it may concern:

Be it known that I, FRANK A. PHILLIPS, a citizen of the United States,residing at Northfield, in the county of Washington and State ofVermont, have invented a new and useful Edge-Lining Machine, of whichthe following is a specification.

' This invention relates to a machine for finishing or edge-lining thecorners of a block of stone, and is particularly adapted to monumentalwork.

In such work it is essential that all of the finished edge surfaces-in asingle face of the block lie in exactly the same plane, a result oftendiflicult to obtain when the different edges are finished in separateoperations.

It is the general object of my invention to provide an edge-liningmachine in which the oppositely disposed edge surfaces in the same faceof the block shall be simultaneously finished. This method of operationsubstantially doubles the output of the machine and improvesthe qualityof the work.

A further object of my invention is to provide a machine in which eachface is cut or ground by a series of successive pairs of cutting wheels,each pair of wheels cutting a little deeper than the preceding pair,

and preferably being of slightly less thickness, thereby. providingclearance for the deeper cuts.

An important feature of my invention relates to the provision ofmechanism by which the upper and lower sets of cutting wheels may bevertically adjusted by varying both the separation and the relativeinclination of the sets of wheels. I further provide an effective andconvenient mechanism by which the individual wheels in each set orseries may be adjusted vertically in relation to the other wheels in theset.

A further object of my invention is to provide means by which thevertical edges of the block may be finished without resetting tlreblock, so that correct alinement of all edges will be secured.

Further features of my invention relate to arrangements and combinationsof parts which will be hereinafter described and 'more particularlypointed out in the appended claims.

A .preferred form of my invention is shown in the drawings, in whichFigure 1 is a front elevation of an edgelining machine embodying myinvention;

Fig. 2 is an enlarged front elevation of a portion of the machine shownin-Fig. 1;

Fig. 3 is a sectional side elevation taken along the line 33 in Fig. 2;

Fig. 9 is a similar view showing the way in which the separate wheeladjusting devices permit the use of wheels of varying diameters Fig. 10is a detail sectional view of a cut made by successive wheels ofdecreasing I width, and

Fig. 11 shows'the appearance of a block of stone after the edges havebeen ground and the surplus stone has been broken off.

Referring to Fig. 1, I have therein shown one form of my improvededge-lining machine in which the operating parts are mounted upon upperand lower beams 20 and 21 supported by posts'or uprights 22' and 23connected at their upper ends by a cross piece 24 and bracedlongitudinally by frame members 25 and 26. The whole structure is firmlysecured togetherby tie-rods 27 and turn buckles 28, said rods beingfirmly secured in the concrete setting of the machine.

A pair of rails 30 extend through the machine and furnish a support fora car 31 (Fig. 3) upon which a block of stone B is supported. Suitabledevices (not shown) are provided for feeding the car longitudinally of.the machine and for varying the rate of feed. These devices may be ofany suitable form and constitute no part of my invention.

Each end of the beam 21 (Fig. 2) is vertically supported by an adjustingscrew 32 threaded into a nut 33 forming part of a cross shaft 34supported in-bearings '35 on the under side of the beam. A handle-.36 isloosely mounted on the upper end of the screw 32 and is connectedthereto by a ratchet 37 and pawlmechanism indicated gen erally at 38. Bythis means the screw 32 may be rotated in either direction to raise orlower one end of the beam 21 manually, and the beam may be firmlysecured in adjusted position by the clamping screws 39.

An adjusting screw 40 is similarly .connected to each end of the upperbeam 20, but means is provided for turning the screws 40 by power,as theupper beam requires much wider adjustment'than the lower beam. Theadjusting'screws 40 are provided with bevel gears. 41 (Figs. 1 and 7) ontheir upper ends, meshing with pinions 42 and 43. The pinion 42 is fixedto a horizontal shaft 44 rotatable in bearings supported by the crossbeam 24 and driven through bevel gears 45 46 from a vertical drive shaft47. This shaft is power-driven, and may be started and stopped asdesired.

The pinion 43 is fixed to a second horizontal shaft 48 mounted on thecross beam 24 and alined with the shaft 44. A clutch collar 49 (Fig. 7)is fixed to the end of the shaft 48 and a clutch sleeve 50 is keyed tothe shaft 44, its position being controlled by a yoke 51 mounted on asliding rod 52 and shiftable longitudinally by manually operatedmechanism not shown.

When the sleeve 50 is moved to the position shown in Fig. 7, the shafts44and 48 are connected together and both ends of the beam 20 will beraised or lowered equally. When it is desired to change the inclinationof the beam, the clutch members are separated and the pinion 42 isrotated to drive the adjusting screw 40 in the desired direction toraise or lower the right-hand end of the beam relative to the left-hand.end. When the desired inclination of the beam is thus secured, theclutch is thrown in and the beam may be raised or lowered bodily tosecure the correct vertical position. As-the vertical adjustment of thelower beam is usually slight, no provision is made for simultaneouslyraising or lowering both ends of this beam.

The mechanism above described provides for adjustment of the upper orlower sets of wheels as a'unit, but it does not provide the necessaryadjustment for each individual wheel. For this purpose I have providedthe mechanism shown in Figs. 3 to 6, in

which it appears that each cutting wheel W (Fig. 4) is mounted on awheel shaft 53 supported in bearings 54 and 55. The upper part of eachbearing comprises an arm 56 angularly movable about the center of a stud57 secured in said arm and mounted in a bearing block 58 bolted to thesupporting beam 20 or 21. The bearings 54 and 55 engage shoulders on thewheel shaft, and the shafts 53 are thus positioned longitudinally byadjusting screws 59 engaging the ends of the studs 57 in the bearings58. By means of these adjusting screws all lost motion may beeliminated, and each wheel may be exactly alined with the other wheelsof the series. I

The position of each swinging arm 56 relative to its supporting beam isdetermined by a stud 60 (Fig. 5) threaded into the end of the arm 56 andengaging a plate 61 bolted to the beam 20 or 21. This stud may beadjusted to limit the approach of the arm 56 to the beam 20, suchadjustment being retained by a check nut 62. A T bolt 63 (Fig. 6)extends through an opening in the plate 61, the lateral extensions ofthe bolt being circular in section as indicated in Fig. 5, and having abearing in the inner face of the plate 61. The bolt extends freelythrough the plate 61 and also through an upwardly enlarged opening inthe arm 56, and is provided at its lower end with a nut 64 by which thearm 56 may be drawn toward the beam 20 or 21 until the correspondingstud 60 engages the plate 61. Movement of the arm in either direction isthereafter prevented. By the provision of two swinging arms for eachshaft, spaced apart a substantial distance on the supporting beam, theshafts are very rigidly held and accurate adjustment thereof may besecured.

In Fig. 8 I have indicated the operation of a series of four successivepairs of cutting wheels upon the upper and lower edges of a block B ofstone fed between the wheels on the car 31. By reference to this figureit will appear that each pair of wheels increases the depth of the cutmade by the preceding wheels. In order that clearance may be providedfor the wheels making the deepest cut, I prefer to decrease the face ofeach successive pair of wheels. The nament would be impossible, but bythe use of the adjusting means herein shown and described the wheels canbe arranged as shown in Fig 9, in which a series of wheels of differentsizes are adjusted to produce the same result as is attained by wheelsof uniform size in Fig. 8.

The mechanism thus far described provides for finishing thelongitudinally extending edges of the block. It is commonly necessary tofinish also the vertical end edges of each face, and for this purpose Iprovide the vertically movable cutting wheel W shown in Fig. 1. As thevertical cut is usually comparatively short, the feed of the wheel isaccomplished manually by a hand wheel 65. The same wheel is used formaking the vertical cut at each end of the block, and as these cuts aremade before the block is moved from its original position upon the carthe four cuts will be found accurately disposed in the same plane if thewheel shafts are properly adjusted longitu dinally.

The several wheels in each series may be driven by belts 66 and 67 (Fig.1), each belt passing around a series of guide pulleys 68 and a seriesof driving ulleys 69 on the separate wheel shafts. T 1e belts 66 and 67may be driven from any suitable source of power, as is also the belt 7 0for the wheel W.

After the edge cuts on one face of'the block are completed, theremaining portion of the stone is broken away, producing a finished facehaving the appearance shown in F ig. 11.

Having thus described my invention, it will be evident that changes andmodifications can be made therein by those skilled in the art withoutdeparting from the spirit and scope thereof as set forth in the claims,and I do not wish to be otherwise limited to the details hereindisclosed, but what I claim is 1. An edge lining machine having, incomto simultaneously adjust both ends of the upper support vertically.

3. An edge lining machine having, in combination, upper and lower setsof grinding wheels disposed in a single plane and engaging oppositefaces of the work, and means to vary both the vertical position and therelative inclination of each set of wheels.

4. An edge lining machine, having, in combination, a series of wheels, asupport therefor, means to raise and lower said support, and means toadjust each wheel separately relative to said support, said meanscomprising swinging bearings for each wheel mounted on said support,means to move each bearing toward said support, and stops to limit suchmovement.

5. An edge lining machine comprising upper and lower sets of grindingwheels, and means to feed stock between said wheels, said wheelsengaging said stock in successive pairs, and each pair being of lessthickness than the preceding pair.

6. An edge lining machine comprising upper and lower sets of grindingwheels, and means to feed stock between said wheels, said wheelsengaging said stock in successive pairs, and the wheels of each pairhaving their cutting edges more closely adjacent than the wheels of thepreceding pair, whereby successively deeper cut are made.

7. An edge lining machine comprising upper and lower sets of grindingwheels, means to support a block of stone as it is moved past saidwheels, and means to adjust the wheels axially, whereby all of thewheels may be made effective to operate simultaneously in a singleplane.

8. An edge lining machine having, in combination, a plurality of wheels,a separate driving shaft for each wheel, a separate set of bearings foreach shaft, and mean to independently adjust each shaft and itsassociated set of bearings axially, whereby the axial position of eachshaft and wheel may be separately determined.

9. An edge lining machine having, in combination, a plurallty of wheels,a driving shaft for each wheel, separate bearings for each shaft, asupport to which saidbearings are pivoted, and means engaging the pivotof each bearing adapted to adjust said pivot and bearing axially,whereby the corresponding Wheel is axially positioned independently ofthe other wheels.

In testimony whereof I have hereunto affixed my signature.
